Thank you very much for trying to help. I've looked through every single cemetery and grave that looks to be near Carrigtwohill, on the Historic Graves site. But not all graveyards are up on that site, so I need to know which graveyards were/are actually associated with Carrigtwohill, and whether those graveyards are on line yet, or whether they are not, so I know where to search next.
Thank you! I am grateful for any ideas or information.
